Microsoft Teams as a platform. You may be familiar with Teams as a collaborative communication tool, but as a developer, you could also view it as a development platform. In fact, Teams provides an alternative way to interact with and distribute your existing web applications.

There are three types of log files automatically produced by the client, which can be leveraged to assist in monitoring and troubleshooting Teams:

This article describes the three logs and how they are used.

For information about troubleshooting specific issues, see: Teams Troubleshooting. For information about how to contact support, see Get support.

When creating a support request with Microsoft Support, the support engineer will require the debug logs. Having the debug logs on hand before creating the support request will allow Microsoft to quickly start troubleshooting the problem. Media or Desktop logs are only required if requested by Microsoft.


In this article, the term Debug logs refers to the logs that are used for troubleshooting. However, the files that are generated for these logs will contain the term diagnostic logs in their names.

The following table outlines the various clients and their associated logs. Log files are stored in locations specific to the client and operating system.

  1. Some browsers, such as Internet Explorer 11, Safari, and Firefox, support the Microsoft Teams web app but don't support some of the Teams calling and meeting features. To work around this limitation, the Teams web app lets users receive audio through a PSTN connection and lets them view presented content (screen share) at a reduced display rate.
  2. Step 1: To download the Microsoft Teams desktop app, return to the Microsoft Teams web page and click on “Download Teams” at the top of your screen. Step 2: Click on the “Download for desktop” button to page jump to the download link for either Mac OS or Windows, depending upon your system. This link will show up as “Download Teams.”.

For a complete list of supported operating systems and browsers, see Get clients for Microsoft Teams.

Debug logs

These are the most common logs and are required for all Microsoft support cases. Debug logs are produced by the Windows and Mac desktop clients, as well as by browser-based clients. The logs are text based and are read from the bottom-up. They can be read using any text-based editor, and new logs are created when logging into the client.

Debug logs show the following data flows:

  • Login

  • Connection requests to middle-tier services

  • Call/conversation

The debug logs are produced using the following OS-specific methods:

  • Windows:

    Keyboard shortcut: Ctrl + Alt + Shift + 1

  • Mac OSX:

    Keyboard shortcut: Option + Command + Shift+1

  • Linux:

    Keyboard shortcut: Ctrl + Alt + Shift + 1

The debug logs are automatically downloaded to the following folders:

  • Windows: %userprofile%Downloads

  • Mac OSX: ~/Downloads

  • Linux: ~/Downloads

  • Browser: You will be prompted to save the debug log to default save location

Media logs

Media logs contain diagnostic data about audio, video, and screen sharing in Teams meetings. They are required for support cases that are linked to call-related issues.

Media logging is turned off by default. To log diagnostic data for Teams meetings, users must turn on the option in the Teams client. Go to Settings > General, select the Enable logging for meeting diagnostics (requires restarting Teams) check box, restart Teams, and reproduce the issue.

The following table outlines the media log locations. When you send the log files to Microsoft support, please verify the timestamp of the log files to ensure the logs cover the time frame when you reproduced the issue.

Mac OSX~/Library/Application Support/Microsoft/Teams/media-stack/*.blog
~/Library/Application Support/Microsoft/Teams/skylib/*.blog
Linux~/.config/Microsoft/Microsoft Teams/media-stack/*.blog
~/.config/Microsoft/Microsoft Teams/skylib/*.blog

Here's a list of the log files that are generated and the information they contain.

Desktop logs

Teams Microsoft Web Browser

Desktop logs, also known as bootstrapper logs, contain log data that occurs between the desktop client and the browser. Like media logs, these logs are only needed if requested by Microsoft. The logs are text based and can be read using any text-based editor in a top-down format.


  • Right-click the Microsoft Teams icon in your system tray, and select Get Logs.

Mac OsX:

  • Choose Get Logs from the Help pull-down menu.


  • Click on the Microsoft Teams icon in your system tray, and select Get Logs.
Mac OSX~/Library/Application Support/Microsoft/Teams/logs.txt
Linux~/.config/Microsoft/Microsoft Teams/logs.txt

Browser trace

For some categories of errors, Microsoft Support might require you to collect a browser trace. This information can provide important details about the state of the Teams client when the error occurs.

Teams Download

Before you start the browser trace, make sure that you’re signed in to Teams. It's important to do this before you start the trace so that the trace doesn't contain sensitive sign-in information.

After you’re signed in, select one of the following links, as appropriate for your browser, and follow the provided steps.


Teams Login

In the steps, replace all references to the Azure portal with the Teams client.
